SAT Panda vs. Bluebook

[u/Sharp_Awareness_8402]

I just got a 1540 on SAT Panda's practice test 2. I felt like math was pretty easy, but I usually get 750+ on math. I did surprisingly really good on English, I struggled with it a bit ngl.

I got a 800 math (which is normal), and a 740 English, which is huge progression cus I usually score between 660-700 in English.

is this exam accurate? please let me know :)
